5.4 Mounting the boiler
Before mounting the boiler, the installer needs to design and calculate the following parts:
•
Flue gas pipe connection.
•
Air supply connection.
•
Flow and return connection.
•
Condensate and pressure relief valve drainage.
•
Power supply.
•
A proper design to control the boiler (room thermostat, 0-10V etc.)
All lines/piping must be mounted free of tension. The weight of all the installation components should be
supported separately from the boiler so there will be no standing force on the connections.
Don't use excessive force on the connections while mounting the boiler.
